Bacterial biofilm formation
Sochorová, Zuzana ; Zikánová, Blanka (referee) ; Weiser, Jaroslav (advisor)
Biofilms are formed by microorganisms living together in a hydrated extracellular matrix. Formation of such clusters of bacteria brings many benefits. The increased resistance to antibiotics is the main one. Creating a biofilm is analogous to the development of multicellular organisms. Biofilm cells communicate with each other with signaling molecules. Signaling molecules make the biofilm more compact structure. Extracellular matrix, in which bacteria live, maintains biofilm structure, affects cell adhesion and protects cells against environmental influences. Bacteria also interact with the environment through the extracellular matrix. The matrix is composed of various biopolymers and proteins. Biofilms are a common cause of infections associated with implants. There are several ways to prevent bacteria in biofilm to antibiotics. These include a slow diffusion of substances, a slow growth or an adaptation to stress. The formation of persistent cells that are tolerant to the antibiotics is the cause of their survival as well as a new population may arise from them. The surface proteins are important elements for the formation of biofilms, they facilitate adhesion and subsequent establishment of biofilm. A protein Bap was the first identified protein. Later its homologues were found, such as BapA,...

The future of a Czech family
SOCHOROVÁ, Zuzana
My work deals with contemporary Czech family and its development. Young people enter to a lesser extent to marry, less and less children are born, the population is aging, alarming is the high number of divorces. Does the impact the amount of education on divorce? Evident is also a large increase in children born to single mothers. Even though it is still the most children born of marriage, unmarried parents are increasing. Many couples can not conceive a child naturally and uses the opportunity to assisted reproduction. Increasing the proportion of women who for some reason a child can not or do not want. i also deal with the division of roles in the family and in the work area. What has changed in contemporary family compared to traditional family? The aim is to map the current situation of Czech families and their future from the perspective of domestic and foreign authors. i can see the importance of the ethical and social aspects that may to impact the influence of development of families in the future.Conclusion contains my assessment on this issue.
